1 Dehumidifier capacity is generally measured by how many pints of water a unit removes from the air in 24 hours. 2  A mini-dehumidifier (1-10 pints) for a bathroom, closet or under a counter usually costs $40-$70.
When talking about size, we mean how much moisture the dehumidifier will remove from the air. That is measured in pints. Most companies that make dehumidifiers offer a few different sizes. For instance, Frigidaire offers a 30 pint dehumidifier, a 50 pint dehumidifier and a 70 pint dehumidifier. A dehumidifier used in a very large space or a very damp space needs to be larger than one used in a small space that is not very damp.
